A cloze worksheet keeps a reading passage visible while removing selected words or phrases. Students fill the gaps by using grammar, meaning, topic knowledge, and the surrounding sentences. That makes the activity different from a vocabulary list or a separate quiz question: the missing answer has to fit back into real text.

Teachers use cloze work for several jobs. Mechanical deletion, such as every sixth or seventh word, checks whether readers can follow the flow of the whole passage. Selected deletion focuses attention on lesson vocabulary, connectors, content terms, verb forms, or phrases that carry one idea. A passage about plants might remove photosynthesis; a geography passage might remove contrast words such as however or whereas.

Context clue: Nearby words, grammar, examples, contrast, and sentence logic that help a reader infer the missing answer.
Blank density: The share of passage words removed. Higher density gives fewer clues and usually makes the worksheet harder.
Word bank: A visible answer pool. It lowers recall demand while still asking students to match words to context.
Selected deletion: Teacher-chosen blanks for specific terms or phrases instead of a purely regular interval.

The amount of support matters as much as the answer list. A word bank turns the task toward matching and context clues. Hiding the bank turns the same passage toward recall. Keeping punctuation beside a blank can preserve grammar clues; removing punctuation can make the answer less obvious. Numbered blanks make marking easier, while wider blanks can hide answer length.

A good cloze worksheet is not just a passage with correct blanks. The surrounding text should leave enough evidence for a reasonable answer, and the blank choices should match the lesson purpose. Too many blanks turn reading into guessing. Too few blanks may not ask students to practice the target skill. A short teacher review before printing catches most density, ambiguity, and support problems.

Common cloze worksheet choices and their teaching effects
Choice	Best Fit	Watch For
Every few words	General comprehension, syntax, and sustained attention.	Minor words can become blanks while important terms stay visible.
Vocabulary targets	Lesson terms in their original sentence context.	Inflected forms, capitalization, or spelling differences can miss a target.
Frequent content words	Repeated ideas that shape the passage topic.	Names or generic repeated words can dominate short passages.
Bracketed phrases	Exact teacher-marked answers that should stay together.	Long phrase blanks may need a word bank or stronger clue text.

Cloze work can support comprehension checks, vocabulary practice, grammar review, and discussion, but it should not be treated as a full reading assessment by itself. When the result affects grades, placement, or intervention decisions, pair the worksheet with another evidence source such as discussion, written response, or teacher observation.

How to Use This Tool:

Start from the passage and lesson purpose, then use the preview and teacher checks to decide whether the handout is ready.

Paste the passage into Passage text or import one plain-text file with Browse TXT. Put brackets around any word or phrase that must become a blank, such as [photosynthesis].
Choose Blanking mode. Every nth word applies a regular interval, Vocabulary list targets entered terms or phrases, Most frequent words uses repeated content words, and Manual bracket syntax only relies on bracketed blanks.
Fill the mode-specific settings. Adjust the interval and lead words, enter vocabulary terms, choose how many frequent terms to target, or mark the exact answers in brackets.
Use Seed when you need the same shuffled word bank for reprints. New seed changes bank order when shuffling is on; it does not choose different blanks.
Set student-facing options such as Show word bank, worksheet title, instructions, blank width, blank numbering, and whether the teacher key appears in print or document export.
Open Advanced for lead words, minimum frequent length, extra stop words, maximum blanks, case-sensitive matching, attached punctuation, word-bank shuffling, and duplicate bank words.
Review the summary badges and tabs. Print, copy, download, or export only after Worksheet, Answer Key, Teacher Check, and Blanking Ledger agree with the lesson goal.

Interpreting Results:

The blank count is the workload students see. Blank density is the better difficulty clue because it compares blanks with passage length. Ten blanks in a short paragraph can be much harder than ten blanks spread through a full page.

How to interpret cloze worksheet density results
Teacher Check Cue	Density Range	Practical Reading	Common Response
`Light practice`	Below 8%	Most words remain visible, so the passage gives many clues.	Add selected targets or lower the interval when students need more recall.
`Balanced`	8% to 22%	The passage usually keeps enough clue text for ordinary context practice.	Review the selected blanks, then print or export if the targets fit the lesson.
`Demanding`	Above 22% to 35%	Students may need prior reading, small-group support, or a visible word bank.	Use for review or stronger readers, or reduce the targets for first exposure.
`Very dense`	Above 35%	The passage may stop functioning as meaningful reading and become guessing.	Raise the interval, shorten the vocabulary list, or set a maximum blank cap.

Missing vocabulary means a target did not match the passage with the current spelling, spacing, word form, and case setting. Phrase blanks counts answers made from more than one word or forced with brackets. Repeated answers points out when the same normalized answer appears more than once, which can make a word bank easier than intended.

The Blanking Ledger is useful when the preview looks uneven. It shows each blank, its selection reason, its passage word number, and whether the answer appears in the bank. If a blank has too little clue text, change the target list, keep more lead words, show the word bank, keep punctuation, or reduce the density.

Warnings should be resolved before student use. They appear when the passage is empty, no blanks were created, vocabulary targets were not found, frequent terms were unavailable, or the maximum blank cap left selected targets visible.

Technical Details:

Cloze generation depends on a passage token stream and a selection rule. Words are counted in reading order, while surrounding punctuation and spacing stay available for the worksheet preview. Bracketed words or phrases act as teacher-forced blanks and are selected even when another automatic mode is active.

Mechanical deletion uses position, so it is repeatable and broad. Vocabulary deletion uses teacher-entered terms, including adjacent phrase matches when the words appear together. Frequent-word deletion ranks repeated content terms after built-in stop words, extra stop words, and minimum length rules are applied. These approaches can produce very different worksheets from the same passage.

Formula Core:

In nth-word deletion, a word is blanked when its passage position falls on the selected interval after the lead words kept visible. Density is the percentage of passage words that become blanks.

blank (w) = 1 if w > L and (w - L) mod n = 0

density = \frac{B}{W} \times 100 %

w is the passage word number, L is lead words to keep, n is the interval, B is blank count, and W is passage word count. With 12 lead words and an interval of 6, words 18, 24, 30, and so on are selected unless a maximum blank cap stops the list.

Transformation Core:

Cloze worksheet blanking modes and selection boundaries
Mode or Setting	Selection Rule	Boundary to Review
`Every nth word`	Blanks every 2nd through 50th word after the configured lead words.	A smaller interval raises density quickly and may remove low-value function words.
`Vocabulary list`	Matches comma, semicolon, or line-separated terms against passage words and adjacent phrases.	Case-sensitive matching decides whether capitalization must match exactly.
`Most frequent words`	Ranks repeated terms after stop words and minimum length are applied, then blanks matching occurrences.	Short passages can overselect names or repeated generic words.
`Manual bracket syntax only`	Uses only bracketed words or phrases from the passage.	Every important blank must be marked in the passage by the teacher.
`Maximum blanks`	Stops adding blanks after the cap is reached, or leaves the list uncapped at zero.	The teacher check reports selected targets that stayed visible because of the cap.
`Seed`	Recreates the shuffled word-bank order when bank shuffling is enabled.	Changing the seed changes bank order, not blank selection.

Phrase matching prefers multi-word vocabulary targets when adjacent passage words match the target sequence. Once a phrase is selected, the answer appears as one answer-key row and the extra words in the phrase are hidden from the worksheet text. Single-word targets continue to match individual words.

Blank width changes the clue level. Fixed-width blanks hide original answer length, while word-length blanks reveal a rough length clue. Keeping attached punctuation leaves commas, quotes, and sentence-ending marks near blanks; hiding punctuation removes those marks when they border a selected answer.

The worksheet preview, word bank, answer key, teacher check, ledger, and JSON report come from the same selected blank list. Copy, print, download, and document export features reformat that list; they do not change which passage words were selected.

Limitations, Privacy, and Accuracy Notes:

The blanking rules are deterministic, but instructional quality still needs human judgment. A valid worksheet can be too hard for the class, too easy with the bank visible, or ambiguous because the passage allows several sensible answers. Read several blanks in context before using the sheet for grades or independent work.

Plain-text import reads the file into the browser, and blank selection is generated from the passage and settings without a server lookup. Browser copy, print, download, and document export actions may still write files to the device, open a print window, or use ordinary browser permissions.

Paste only passages you are allowed to adapt. Keep student names, private notes, and restricted copyrighted text out of shared examples unless your school or organization permits that use.

Worked Examples:

A 180-word science passage with 12 lead words and every 6th word blanked creates 28 blanks. The density is about 15.6%, which should read as balanced if the selected words still have useful context around them.

A vocabulary worksheet can target water cycle, evaporation, and condensation. If water cycle appears as adjacent words, it becomes one phrase blank and one answer-key row. If the passage says water cycles, the target list needs the matching word form.

A short story may produce weak frequent-word targets because character names repeat more often than lesson concepts. Add those names to Extra stop words, raise the minimum frequent length, or mark the desired words directly with brackets.

For a student-only handout, hide the teacher key from print and keep the word bank visible only when students need scaffolding. For a review packet, include the teacher key in the exported document so marking notes stay attached to the worksheet.

FAQ:

Can I force one specific word or phrase to become a blank?

Yes. Put the answer in brackets inside Passage text, such as [photosynthesis]. Bracketed answers are selected even when another blanking mode is active.

Why did my vocabulary term not blank out?

Check spelling, word form, spacing, phrase order, and Case-sensitive matching. The Missing vocabulary row lists targets that were not found with the current settings.

Does the word bank always show every removed word?

Only when Show word bank is on. Repeated answers appear once by default, but Keep duplicate bank words can keep repeats visible. The answer key still keeps every blank in passage order.

Why does changing the seed change the word bank but not the blanks?

The seed controls shuffled bank order when shuffling is enabled. Blank selection comes from the passage, mode, targets, brackets, and advanced settings.

Can this be used as a comprehension test?

It can support a comprehension check, but it is not a full reading assessment by itself. Use discussion, written responses, oral reading, or another check when the result affects grades or placement.

Can it choose grade-level blanks automatically?

No. It selects blanks by interval, vocabulary targets, frequent terms, or brackets. A teacher still decides whether the passage, supports, and answer expectations fit the learners.
